The self-priming ability of the gear pump exists but has limitations. In practical applications, it is necessary to fully consider various influencing factors and take corresponding measures to improve its self-priming performance to meet specific work requirements.

The performance evaluation of a centrifugal pump is a complex and systematic process that requires comprehensive consideration of multiple factors and the use of appropriate evaluation methods. Through scientific evaluation and optimization measures, it can be ensured that the centrifugal pump can operate efficiently, stably, and perform at its best in actual applications.

The marine centrifugal pump drives the impeller to rotate at high speed through the motor, and uses centrifugal force to throw the liquid from the center of the impeller to the outer edge and discharge it under pressure, realizing the continuous transportation of liquid.

The selection rules for large-flow double-suction pumps are a process that comprehensively considers multiple factors. It requires clarifying the needs, selecting pump types, considering economy and reliability, and paying attention to other related matters.

There are many types of mechanical seal leakage in centrifugal pumps, which need to be analyzed and handled according to the specific situation.

There are many types of mechanical seal leakage in centrifugal pumps, which need to be analyzed and handled according to the specific situation.

The labyrinth seal of the water pump is an efficient and reliable sealing method with broad application prospects. During use, attention should be paid to gap control, material selection and environmental protection to ensure its good sealing performance and service life.

There are many different forms of sealing for water pumps, each with its own advantages and disadvantages. In practical applications, the appropriate sealing form should be selected according to the specific situation to ensure the normal operation and long-term stability of the water pump.

In summary, the selection of water pump materials needs to be comprehensively considered according to specific factors. In the selection process, the advantages and disadvantages and applicable scope of various materials should be fully understood in order to make a reasonable choice.

There are many reasons for leakage of centrifugal pumps. When solving the leakage problem, appropriate measures should be taken according to the specific situation, such as replacing seals, optimizing the pump structure, adjusting working conditions or strengthening operation and maintenance.
